Bockman Brothers Gemstones


Gemstones are beautiful and incredibly popular. In fact long before diamonds exploded onto the scene jewelry was typically made of gemstones. Throughout history rubies, sapphires, emeralds, and other stones have always been sought after. The bright colors and shades give these stones a unique identity, and offer an alternative to diamonds.


If you are looking for gemstone jewelry in the Aurora, Naperville, or western suburbs of Chicago then Bockman Brothers should be your first stop. We have a huge selection of precious and semi precious gemstones to choose from. We offer gemstone rings, earrings, pendants, and more.

 

Precious Gemstones
Only three of the colored gemstones on the market are considered precious. Those three are ruby, sapphire, and emerald. Because of their brilliant colors, and rarity these jewels have remained a favorite for hundreds of years. Perfect precious stones with a good size are extremely hard to come by. Because of this it is common to see stones with lower clarity than diamonds.
Semi-precious gemstones
Any jewel that does not fall into the sapphire, ruby, or emerald category is considered a semi precious gemstone. Prices on these stones can vary depending upon the material being used. Black Opal is somewhat rare and therefore more expensive. Semi-precious stones come in a wide variety of colors, and choices making it ideal for custom jewelry.
Lab Create Stones
Synthetic gemstones are grown in a laboratory rather than in nature. Bockman Brothers is proud to say that they do not carry any lab created stones. We pride ourselves on providing only top quality jewelry to our clients.
